Command Line Interface Reference for the ProSafe 7300 Series Layer-3 Switches, Software Ver- 2.2.3 Slot-Port Naming Convention 7300 Series Managed Switch software references physical entities such as cards and ports by using a Slot-Port (SP) naming convention. The software also uses this convention to identify certain logical entities, such as port-channel interfaces. The slot number has two uses. In the case of physical ports, it identifies the card containing the ports. In the case of logical and CPU ports it also identifies the type of interface or port. Table 2-3. Type of Slots Slot Type Physical slot numbers Logical slot numbers CPU slot numbers Description Physical slot numbers begin with zero, and are allocated up to the maximum number of physical slots. Logical slots immediately follow physical slots and identify portchannel (LAG) or router interfaces. The CPU slots immediately follow the logical slots. The port identifies the specific physical port or logical interface being managed on a given slot. Table 2-4. Type of Ports Port Type Physical Ports Logical Interfaces CPU ports Description The physical ports for each slot are numbered sequentially starting from zero. Port-channel or Link Aggregation Group (LAG) interfaces are logical interfaces that are only used for bridging functions. VLAN routing interfaces are only used for routing functions. CPU ports are handled by the driver as one or more physical entities located on physical slots. 2.2.4 Using the "No" Form of a Command The no keyword is a specific form of an existing command and does not represent a new or distinct command. Almost every configuration command has a no form. In general, use the no form to reverse the action of a command or reset a value back to the default. For example, the no shutdown configuration command reverses the shutdown of an interface. Use the command without the keyword no to re-enable a disabled feature or to enable a feature that is disabled by default. Only the configuration commands are available in the no form.

Overview
2-5
v1.0, February 2007
2.2.3
Slot-Port Naming Convention
7300 Series Managed Switch software references physical entities such as cards and ports
by using a Slot-Port (SP) naming convention. The software also uses this convention to
identify certain logical entities, such as port-channel interfaces.
The slot number has two uses. In the case of physical ports, it identifies the card
containing the ports. In the case of logical and CPU ports it also identifies the type of
interface or port.
The port identifies the specific physical port or logical interface being managed on a given
slot.
2.2.4
Using the “No” Form of a Command
The
no
keyword is a specific form of an existing command and does not represent a new
or distinct command. Almost every configuration command has a
no
form. In general, use
the
no
form to reverse the action of a command or reset a value back to the default. For
example, the
no shutdown
configuration command reverses the shutdown of an interface.
Use the command without the keyword
no
to re-enable a disabled feature or to enable a
feature that is disabled by default.
Only the configuration commands are available in the
no
form.
Table 2-3. Type of Slots
Slot Type
Description
Physical slot numbers
Physical slot numbers begin with zero, and are allocated up to the
maximum number of physical slots.
Logical slot numbers
Logical slots immediately follow physical slots and identify port-
channel (LAG) or router interfaces.
CPU slot numbers
The CPU slots immediately follow the logical slots.
Table 2-4. Type of Ports
Port Type
Description
Physical Ports
The physical ports for each slot are numbered sequentially starting
from zero.
Logical Interfaces
Port-channel or Link Aggregation Group (LAG) interfaces are
logical interfaces that are only used for bridging functions.
VLAN routing interfaces are only used for routing functions.
CPU ports
CPU ports are handled by the driver as one or more physical
entities located on physical slots.
